01. App access

Once you open the app, the first step will be to set up your access PIN — a 4-digit code that you choose yourself.

Cuvex does not request any personal information. If you lose your phone or are unable to access the app, you will need to download it again and re-link your cards. In other words, no data is shared with or stored on Cuvex servers. All information entered into the Cuvex app is stored locally in your smartphone’s secure element, which means there is no account recovery service.

You can also enable access using your smartphone’s native biometric authentication either during the initial setup or later via the Security section.

04. Encrypt a Secret via NFC from the App

Step 1: From the app’s main menu, tap the “Encrypt Secret via NFC” button. The app will prompt you to remove your SIM card and enable airplane mode to block internet access.

Next, enter the text you wish to encrypt. Cuvex currently supports up to 500 characters.
Then, hold a new Cuvex NFC card near your smartphone’s NFC reader.

Step 2: It’s very important to note that the information is not yet encrypted at this stage.
You must now go to your Cuvex device and follow this path:

Encrypt → Text from NFC, then follow the encryption flow to securely protect your secret.

05. Security

Change Mobile App PIN

From the app’s main menu, tap the “Security” button. Once inside, select “Change PIN”. The app will prompt you to enter your current PIN. Remember, this is the PIN used to access the mobile app.

Note: If you don’t remember your access PIN, you can delete and reinstall the app. Keep in mind that the app does not store any data, so you’ll need to re-link your card(s) and reactivate your Watch-Only Wallet if it was previously enabled.

We strongly recommend making periodic backups of your Watch-Only Wallet Labels. This file allows you to restore all your wallets simply by importing it when transferring your wallet to another smartphone.

Next, enter your new PIN and repeat it to avoid any typing errors. That’s it you’re all set to access the app again.

B) Validate Traceability

The codes on your stickers can be authenticated within the Cuvex App.
Go to the Security section: Menu > Validate Traceability. Enter the codes printed on both seals and tap Validate.

If the box shows any signs of having been opened, peeled off stickers with evidence of the word VOID, remains of previous labels or the codes of these seals are not authenticated in the Cuvex App, the customer must contact the company and not use the device.
